In a computer-implemented method for upgrading a fault tolerant hyper-converged infrastructure in an environment with no additional physical infrastructure, a workload domain having a plurality of hosts is chosen for an upgrade. One or more conflict groups are calculated for each host, and a physical host in the workload domain is selected. A number and a size of one or more nested hosts is determined and a different nested host is created in a management cluster for each of the one more conflict groups in the physical host. A communication network provides communication between a virtual machine (VM) on the different nested host and a VM in the physical host. The physical host is put into a maintenance mode, upgraded, and then returned from the maintenance mode to an operational mode.

Fault tolerant hyper-converged infrastructure upgrades in an environment with no additional physical infrastructure

In a computer-implemented method for using a nested host manager in a hyper converged infrastructure to streamline the upgrade process for one or more hosts in a workload domain, a first workload domain having one or more hosts is chosen, and at least one host of the one or more hosts is designated for an upgrade. The resource allotment of the at least one host is evaluated and a nested host having a comparable resource allotment is selected and provided in a second workload domain. Communication is redirected from the at least one host to the nested host. The at least one host is placed in a maintenance mode, updated, and returned to an operational mode.

Nested host manager in a hyper-converged infrastructure

Systems and methods herein can provide virtual resource management for hyper-converged infrastructures. In an example, a method can include identifying an overloaded cluster requesting at least one resource, the overloaded cluster including a hypervisor on a virtual machine. The method can further include identifying an additional cluster having a free resource corresponding to the requested resource. The method can include instantiating a nested host on the additional cluster, the nested host being configured to provide the free resource and the nested hosted comprising an additional hypervisor that manages an additional virtual machine. Further, the method can include registering the nested host with the overloaded cluster such that the overloaded cluster is authorized to use the free resource.

Systems and methods for cluster resource balancing in a hyper-converged infrastructure

A network appliance deployed in a visibility fabric may intelligently drop certain low priority traffic to avoid indiscriminate dropping of data packets across all flow maps during periods of high congestion. More specifically, the network appliance may determine the data packets of a flow map should be dropped based on priority measures assigned on a per-flow map basis. Such a technique enables the network appliance to drop low priority traffic and forward high priority traffic downstream. Also introduced herein are techniques for metering traffic in order to gain better control over the traffic that is forwarded to an egress port of a network appliance. Because a network tool connected to the egress port can become easily overwhelmed, the network appliance may filter the traffic based on the priority of the flow maps to ensure that the network tool does not receive more traffic than can be handled.

Intelligent dropping of packets in a network visibility fabric

Introduced here is a technique for using a network switch device, which may include commodity switching fabric, to route packets through an inline tool, without introducing any additional information to the packets. The introduced technique modifies standard capability of packet forwarding and learning port-to-MAC address associations to route data packets through the inline tool. The technique may include applying two override settings to the network device. A first override setting involves a forwarding rule that is based on the arrival port and the content of the packet. A second override setting involves disabling the MAC address learning mechanism for the packet received from the inline tool via the second tool port of the network device.
